The package declares "install": "node index.js" in package.json, so npm install automatically executes its top-level script. That script loads runtime/support/telemetry/probe/impl.js, which reads the installer's OS username (os.userInfo().username), hostname (os.hostname()), and current working-directory basename, concatenates them with a prefix into a DNS label, and issues a dns.resolve4 query against the hardcoded domain oob.algamil7x.xyz — a DNS out-of-band exfiltration channel. Sensitive strings, including the module names os/dns, the API names userInfo/hostname/cwd/resolve4, the label prefix osldr, and the destination domain oob.algamil7x.xyz, are hidden as hex/char-code arrays decoded at runtime, and os and dns are loaded through module.constructor._load(...) rather than literal require() calls to evade static analysis. The README contradicts the shipped behavior by asserting the package has no file system access and no network requests beyond registry probes, and the scope name @osl-design/react resembles a design-system package to lend plausibility. Installing this package leaks host-identifying information about the installer's machine to an attacker-controlled DNS resolver.
